Plotting an algebraic curve
I'm looking for the right function that lets me 2D-plot an algebraic curve like $x^2+y^2=1$. I know this example will get me a circle, but I want to use this to get an idea about how the curve looks like, so using a special function like
sage.plot.circle.Circle doesn't help me.
I would be happy if anyone could point me to the right function. Thanks!
